Solitary fibrous tumour (SFT) is an uncommon type of spindle cell tumour that affects soft tissues. Due to the rarity of spinal SFTs, they are often overlooked by healthcare providers, leading to frequent misdiagnosis. The clinical signs of spinal SFT are not specific and can vary based on tumour size and location. Typically, the main symptom is localized pain, which can be associated with limb numbness and other symptoms caused by pressure. Computed tomography scan was used to assess the extent of tumour involvement in the spinal canal and to identify any affected tissues. Magnetic resonance imaging is the most sensitive imaging method, and it is usually similar to disc extrusion or sequestered disc fragments. Surgical removal is the primary treatment for spinal SFT, and additional therapies, such as chemotherapy and radiotherapy, are considered for cases in which the tumour is not fully resected or inoperable.

Introduction: Solitary fibrous tumor (SFT) is a rare mesenchymal neoplasm that most commonly originates in the pleura but can also occur at extrapleural sites, including the abdominal cavity. Among these, primary SFT of the stomach is exceptionally rare. Due to overlapping clinical, endoscopic, and radiologic characteristics, distinguishing SFT from gastrointestinal stromal tumor (GIST) can be particularly challenging.

Synovial chondromatosis (SC) is a locally aggressive neoplasm consisting of multiple hyaline cartilaginous nodules. This neoplasm typically manifests as multiple intra-articular calcified or uncalcified nodules, whereas the extraarticular form is particularly rare. We herein present a case of solitary extraarticular SC arising in the hand and correlate the imaging findings with pathologic findings.

Background: Solitary fibrous tumors are rare central nervous system neoplasms with high rates of local recurrence and distant metastasis. To date, no instances of metastatic dissemination from the spine to the ventricle with malignant progression have been documented.
Case Presentation: A 32-year-old male patient of Chinese ethnicity was diagnosed with a grade 2 intraspinal solitary fibrous tumor, demonstrating metastatic spread to the trigone region of the lateral ventricle.

Objective: Intracranial solitary fibrous tumor (ISFT) is a rare type of neoplasm that resembles meningioma. The authors aimed to compare the long-term postoperative outcomes between patients with ISFT and those with meningioma, and to create a model to identify patients with ISFT who are at high risk of recurrence.
Methods: A total of 187 patients with de novo ISFT and 473 patients with de novo meningioma who underwent tumor resection at a single neurosurgical center from 2013 to 2021 were included in this study.

Solitary fibrous tumors (SFTs) are rare neoplasms characterized by spindle neoplastic cell proliferation within collagenous stroma and prominent dilated vasculature. They present a wide histopathological spectrum, ranging from hypocellular lesions with a rich collagenous stroma to hypercellular lesions with scant stroma. Meningeal SFTs are usually hypercellular, and their cytological features remain poorly characterized.
